Description

FIELD OF INVENTION
The present invention relates to insulated beverage containers, and more particularly to beverage containers having a removable stopper.
BACKGROUND
Some previously implemented beverage containers, such as beverage container assembly 10 shown in FIG. 1, include a container main body 11, an inner wall 12 and an outer wall 14 that may be separated by an insulating section 15 that helps to insulate against temperature change of the beverage container's contents. The beverage container assembly 10 may include a stopper 16 that may be removably attached to the container main body 11 to cover or seal a beverage aperture 18 through which liquid may flow. When the stopper 16 is positioned within the beverage aperture 18, a seam 17 is formed between the beverage container main body 11 and the stopper that is exposed to the external environment near the top of the beverage container main body where the inner wall 12 and the outer wall 14 meet. Heat from the beverage container contents may be conducted through the inner wall 12 along the path P and radiate outward at the seam 17 as heat radiation R1. Heat may be further conducted downwardly along the outer wall 14 and radiate outward as heat radiation R2 along the length of the outer wall. A representation of a thermal image of thermal radiation from a beverage container (such as described with respect to beverage container 10) is shown in FIG. 2, which identifies several thermal readings. The largest area of heat radiation is from the area labelled as Section 1, which is around the seam 17. Section 2 and Section 3 radiate less heat than Section 1. This thermal transfer between the beverage container contents and the outside environment occurs regardless of the thermal insulating capability of the stopper 16 covering the beverage aperture 18 of the beverage container 10.

 DETAILED DESCRIPTION
A beverage container assembly 20 according to a first embodiment is shown in FIGS. 3, 4 and 5. The beverage container assembly 20 includes a beverage container body 22 having a lower body portion 23 containing a beverage cavity 24, a beverage container aperture 28 in fluid communication with the beverage cavity and an upper body portion 32 with an upper body portion passageway 29 extending between and in fluid communication with the beverage cavity and an upwardly opening end portion 29A of the upper body portion passageway. The beverage container assembly 20 further includes a stopper member 26 removably attached to the upper body portion 32 and positioned at least partially within the upper body portion passageway 29 for sealing the beverage container aperture 28, and a thermal insulation member 30 removably attached to the upper body portion 32. When the stopper member 26 is sealingly positioned in the upper body portion passageway 29 the stopper seals the beverage container aperture 28 and helps thermally insulate any fluid contained in the beverage cavity 24. The thermal insulation member 30 is removably attachable to the upper body portion 32 and serves as a cover for the beverage container body 22 and provides an insulated enclosure around the stopper member 26 and/or the beverage container aperture 28, and a seam 33 (described below), which helps to further insulate the fluid in the beverage cavity 24, as more fully described below. The thermal insulation member 30 may be a walled cover that, when the attached to the upper body portion 32, provides unexpectedly superior thermal insulation properties compared to a beverage container assembly having only a stopper member for covering the beverage aperture, such as the beverage container assembly 10 of FIG. 1.
The lower body portion 23 of the beverage container body 22 may have an inner sidewall 34 extending downwardly from an upper end portion 23A of the lower body portion and enclosing the beverage cavity 24. The inner sidewall 34 may taper inwardly toward the beverage aperture 28. The lower body portion 23 may include an outer sidewall 35 peripherally spaced apart from the inner sidewall 34 and defining an outer cylindrical portion of the lower body portion 23. A lower insulation portion 37 may be provided between the inner sidewall 34 and the outer sidewall 35. The lower insulation portion 37 may be a vacuum-sealed chamber or may include an insulation material, such as Styrofoam, polyurethane, polyethylene, fiberglass or other insulation material known in the art.
The upper body portion 32 extends upwardly from the upper end portion 23A of the lower body portion 23 and from the beverage container aperture 28. The upper body portion 32 may comprise a generally cylindrically shaped double-walled structure having an upper portion inner wall 38 defining the upper body portion passageway 29, and an upper portion outer wall 42 peripherally spaced apart from the upper portion inner wall 38. The upper body portion 32 may include an upper insulation portion 44 disposed between the upper portion inner wall 38 and the upper portion outer wall 42. The upper insulation portion 44 may be vacuum sealed portion or may include an insulation material described above. The upper portion inner wall 38 and the upper portion outer wall 42 are connected or join at a joint 45 at an upper end portion of the upper body portion 32, located at the upwardly opening end portion 29A of the upper body portion passageway 29.
The stopper member 26 may have a generally cylindrical shaped stopper sidewall 46 extending downwardly from a stopper upper portion 48. The stopper sidewall 46 is sized and shaped to tightly fit within the upper body portion passageway 29 and may abut the upper portion inner wall 38 to close the passageway and seal the beverage cavity 24. The stopper sidewall 46 may include first main body engagement portion 50 adapted to engage with a stopper member engagement portion 52 of the upper body portion 32 to removably secure the stopper member 26 within the upper body portion passageway 29. When the stopper member 26 is secured within the upper body portion passageway 29, the seam 33 is formed between the upper body portion 32 and the stopper upper portion 48. Heat from beverage in the beverage cavity 24 may be conducted upward through the inner sidewall 34, through the upper portion inner wall 38, and radiate outward at the seam 33. From the seam 33, heat may be conducted downward along and radiate from the upper portion outer wall 42.
In the present embodiment, the first main body engagement portion 50 of the stopper sidewall 46 and the stopper member engagement portion 52 of the upper body portion 32 are complementary threaded portions that are threadably engaged when the stopper member 26 is inserted into and rotated within the upper body portion passageway 29. In some embodiments, the first main body engagement portion 50 and the stopper member engagement portion 52 may removably secure the stopper member 26 within the upper body portion passageway 29 by other methods, such as a bayonet mount or friction fit, by way of non-limiting example. The stopper upper portion 48 may include a grip portion 54 for positioning and/or rotating the stopper member 26 within the upper body portion passageway 29. The stopper member 26 may further include a stopper insulation portion 56 provided in the space within the stopper sidewall 46 and having a stopper insulation chamber 58 for thermally insulating fluid in the beverage cavity 24 from an environment external to the beverage container assembly 20. The insulation chamber 58 may be disposed above a stopper member lower end 60 positioned at or in the beverage container aperture 28 when the stopper member 26 is secured within the upper body portion passageway 29.
The thermal insulation member 30 may have a cylindrical shape and include an insulation member sidewall portion 62 extending downwardly from an insulation member upper portion 64, as shown in FIG. 4. When the thermal insulation member 30 is removably secured to the upper body portion 32, the insulation member upper portion 64 is positioned above the beverage aperture 28 and the stopper member upper portion 48, and the insulation member sidewall portion 62 extends fully about the upper body portion 32, the joint 45 and the seam 33. The insulation member sidewall portion 62 may encompass the entire length of the upper body portion 32 down to the upper end portion 23A of the lower body portion 23. The upper portion 64 includes an upper portion inner wall 66 on a lower side thereof and an upper portion outer wall 68 above the upper portion inner wall 66. The insulation member sidewall portion 62 includes a sidewall inner wall 70 extending downwardly from the upper portion inner wall 66 and a sidewall outer wall 72 extending downwardly from the upper portion outer wall 68. An insulated cavity 65 may be formed between the thermal insulation member 30 and the stopper member 26 and/or the main body upper portion 32 when the thermal insulation member is attached to the beverage container main body 22. The upper portion inner wall 66, the upper portion outer wall 68, the sidewall inner wall 70 and the sidewall outer wall 72 may be comprised of a rigid, durable material, such as plastic or metal (e.g., aluminum).
The thermal insulation member 30 includes a thermal member insulation chamber 74 disposed between the upper portion inner wall 66, the upper portion outer wall 68, the sidewall inner wall 70 and the sidewall outer wall 72, for further insulating the stopper member 26 and the upper body portion 32. The thermal member insulation chamber 74 helps to retain heat that is conducted through the upper body portion 32 and/or passing through the joint 45, the seam 33 and the upper portion outer wall 42, and to prevent heat loss from the beverage container assembly 10. The thermal member insulation chamber 74 of the present embodiment is a vacuum sealed chamber having an insulating value higher than air or standard foam. The thermal conductivity of the thermal member insulation chamber 74 is 0.016 W/(m*K) or lower. Alternatively, the chamber 74 may contain a thermal insulation material with a low thermal conductivity, such as such as air, Styrofoam, polyurethane, polyethylene, fiberglass or other insulation material known in the art. The thermal member insulation chamber 74 contains heat and forms a more isolated system than the beverage container assembly 10 since it reduces the exchange of heat with the external environment.
The sidewall inner wall 70 and the sidewall outer wall 72 join at a sidewall end portion 76 at a lower end 78 of the thermal insulation member 30. When the thermal insulation member 30 is attached to the upper body portion 32, the end 78 of the sidewall end portion 76 may be adjacent to or abut an upper annular surface 79 of the upper end portion 23A of the lower body portion 33 to seal a cavity lower portion 65L of the cavity 65. The sidewall end portion 76 may include a soft, elastically deformable material on an exterior surface thereof that deforms when the end 78 is pressed against the upper end portion 23A of the lower body portion 23, helping to create an airtight seal. The end 78 may include a joint or seam at which the sidewall inner wall 70 and sidewall outer wall 72 are bonded together. Alternatively, the sidewall end portion 76 may comprise a continuous portion where the downwardly extending sidewall inner wall 70 bends or curves 180° at the end 78 to form the upwardly extending sidewall outer wall 72.
The insulation member sidewall portion 62 of the thermal insulation member 30 may include a second main body engagement portion 80 for attaching the thermal insulation member to the upper body portion 32. In the present embodiment, the second main body engagement portion 80 is a threaded portion provided on the sidewall inner wall 70. The second main body engagement portion 80 is adapted to engage with a complementary threaded thermal member engagement portion 82 on the upper portion outer wall 42 of the upper body portion 32. The threaded engagement between the second main body engagement portion 80 and the thermal member engagement portion 82 may create a barrier separating the cavity 65 and the lower cavity 65L. Other methods of attachment are contemplated, such as a bayonet mount or corresponding ferromagnetic elements provided in the thermal insulation member 30 and the upper body portion 32. In some embodiments, the thermal member engagement portion 82 may be provided on an upper surface of the lower body portion 23 of the beverage container body 22 at a location at or below the upper end portion 23A.
When engaged, the second main body engagement portion 80 and the thermal member engagement portion 82 comprise a connection area C between the upper body portion 32 and the thermal insulation member 30. The connection area C is spaced apart from the joint 45 at a distance such that a minimal amount of heat is conducted directly through the upper portion outer wall 42 to the sidewall inner wall 70 of the thermal insulation member 30. The thermal member engagement portion 82 may be positioned closer to the upper end portion 23A of the lower body portion 23 than the joint 45 or the seam 33 or the joint 45. The position of the connection area C minimizes the heat loss of a beverage within the beverage cavity 24 of the lower body portion 23 via heat conduction through the walls of the beverage container body 22. The insulation (e.g., vacuum sealed, or insulation material) of the thermal insulation member 30 minimizes heat loss of the contents of the upper body portion 32 by blocking significant convection and radiation that can occur around the joint 45, the seam 33 or the upper portion outer wall 42 compared with a beverage container having an exposed joint between the stopper and the upper body portion which receives the stopper, such as the beverage container 10 of FIG. 1.
While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from this invention and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this invention. Furthermore, it is to be understood that the invention is solely defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.).
It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Accordingly, the invention is not limited except as by the appended claims.
